LIQUID-DISPENSING APPARATUS.

Application filed June 21, 1924. Serial No. 721,484.

This invention relates to a liquid dispensing apparatus and moreparticularly to means for controlling the operation of a registeringdevice associated with' such an apparatus. 1

Liquid dispensing apparatuses, such as gasoline pumps, are commonlyprovided with a device to register the amount of liquid dispensedthereby, this registering device heing controlled by the operation ofthe pumping mechanism. Such pumps are also sometimes provided withaudible signals which are sounded upon the-comp etion of the delivery ofeach specified quantity of liquid.

Certain types ofdispensing apparatus are also provided with means fordisconnecting the cylinder, 01'' cylinders, from the discharge line andfor connecting the same with the tank or inlet end of the cylinders,this being for the purpose of permitting the pump piston to be restoredto its initial position, at one end of the cylinder, when the deliveryhas been completed with the piston in an intermediate position as whenthe amount of liquid delivered involves a fraction of the quantity whichwould be delivered by the pump upon a full stroke of the piston.Inasmuch as the liquid which is thus by-passed or returned to the tankwould not be sold it is desirable that it should not beregistered on theregistering device.

Therefore, one object of the present invention is to provide meanscontrolled by the by-pass valve for rendering the registeringdevice'inoperative when the ,pump cylinder is connected with theby-pass, and disconnected from the discharge line, The term by-pass asherein. employed, is intended to include any conduit through which theliquid may be diverted to a point of delivery, other than the usualdischarge line, and the term by-pass valve is intended to include anydevice for controlling the diversion of liquid through the by-pass.

A further object of the invention is'to pro-. vide means controlled bythe by-pass valve for rendering the audible signal inoperative.

A further object of the invention is to provide'such a mechanism whichwill be simple in its construction, positive in its operation, and whichwill not interfere with the normal operation of the pumping mechanism orthe registering device.

Other objects of theinvention will appear as the apparatus is describedin detail.

In the accompanying drawings Fig. 1 is a front elevation, partly brokenaway, of a dispensing apparatus showing our invention applied thereto;Fig. 2 is a side elevation of i the connecting mechanism between theregis- 6 tering device and the pumping mechanism; Fig. 3-is a top planview of such a connecting mechanism; Fig. 4 is a front elevation of adispensing apparatus showing the modified form of the invention appliedthereto; Fig. 5 is a detail view of the connecting mechanism of saidmodified form of the apparatus, showing the same inits operativeposition; Fig.- 6 is a similar view showing the connec-. tion mechanismin its inoperative position; Fig. 7 is a side elevation of theconnecting mechanism of the apparatus shown in Fig. 4; Fig. 8 is a lanview of the same; and Fig. 9 is a sectional view taken on the line 99 ofFig. 7. v

In these drawings we have illustrated two embodiments of our invention,operating on the same principles but difiering somewhat in construction,and have shown both embodiments as applied, to a double 0' lindergasoline pump. It will be unde'rstoo however, that these two embodimentshave been .chosen for the purpose of illustration only and that theapparatus may take various form's, and maybe applied to liquiddispensing devices of various kindswithout departing from the spirit ofthe invention.

Both embodiments of the invention are shown as ap lied to a doublecylinder gasoline pump 0 a well known construction and comprisingcylinders 1 connected at their upper ends with a single dischar e line 2through which the liquid may be de ivered to a suitable pointofdischarge, this discharge line being usually connected with a flexiblehose, the nozzle of which may be inserted in the receptacle to'befilled. Mounted in each, cylinder is the usual piston, which is not hereshown, but which is actuated by a piston rod 3 having connectedtherewith and forming a part thereof a toothed rael'rfi i. The teeth ofthe two I'flCkSWIOBSh with'the opposite edges of a driving gear 5, shownin dotted lines in Fig. 4 as mounted on a shaft 6. This gear isoperatively connected with a suitable source of power, such as a.

crank 7, also shown in Fig. 4. The drivin connections between the sourceof power an the gear 5 may be of any suitable character and inasmuch asthey do not form any part of the present invention they are not shown ordescribed. The cylinders are also provided at their .upper ends with abyass controlled by a valve 8, by means of w rich the connection betweenthe cylinders and the discharge'line 2 may be interrupted-and thecylinders connected with a conduit or line leading back to the tank orto some pomt of discharge other than the discharge line. The bypass andits controlling valve form no part of the present invention and are nothere shown or described in detail but are similar in character to thoseshown in Patent No. 1,352,664, granted September 14, 1920, to W. T.Hatmaker. It will benoted that the upper ends of the two cylinders aremounted in a casting 9 having an upwardly extending portion in which thebypass valve 8 is mounted, the valve stem 10 extending above thiscasting and being, in the present instance, arranged in a substantiallyvertical position.

Extending upwardly into the casting 9 are suitable uprights or standards11 which support at their upper ends a frame 12. Mounted on this frame,at the top of the apparatus, is a registering apparatus which, as hereshown, comprises a stationary dial 13 and a pointer 14 mounted on theshaft 15 for movement over the dial. The actuating device for theregistering apparatus comprises a ratchet wheel 16 rigidly secured tothe shaft 15 in the rear of the dial and cooperating with this ratchetwheel is a pawl 17 mounted on a pawl carrying arm 18, which is pivotallymounted on a fixed axisat 19. The pawl carrying arm 18 and the shaft 15are here shown as mounted on a bracket 20 extending upwardly from theframe 12. Connected with the pawl carrying arm 18 and, if desired,formed integral therewith, is an operating arm 21 which is adapted to beconnected with the pumping mechanism in such a manner that theregisteringdevice will be actuated in accordance with the amount ofliquid delivered by the pump through the discharge line.

The connection between the actuating device for the register and thepumping apparatus may take any suitable form but it preferably comprisesamovable part which, when in one position will render the connectionoperative and when in another position will render the connectioninoperative, and the position of this movable part is controlled by theposition of the by-pass valve 8. In both forms of the apparatus hereshown the connecting mechanism comprises an arm pivotally mounted on afixed axis and having one end connected with the operating arm 21 of theactuatin d i f r th register. This arm is connected with the piunpingmechanism, preferably through the medium of a cam, in such a manner thatthe connecting arm .will make one complete oscillation about its axisand thereby impart one complete movement to the registering device uponthe delivery of each specified quantity of liquid. That part of theconnection which is moved to control the operation thereof may beinterposed either between the arm and the register actuating device orbetween the arm and the pumping mechanism.

In that form of the apparatus shown in Figs. 1 to 3, the movable part isinter osed between the arm and the actuating tevice for the register. Inthis form of the device the connecting arm is shown at 22 as mounted ona fixed axis, and preferably it is mounted on a stud 23 carried by abracket 24 secured to the frame 12. This arm is acted upon at a pointspaced from its axis by a cam which is operatively connected with thepumping mechanism and is so arranged as to impart one complete movementto the arm upon the delivery of each specified quantity of liquid. Thearm may make one complete movement for each complete stroke of one ofthe pistons or it may make more than one complete movement during eachstroke of the piston but in either instance each complete movement ofthe arm represents a definite quantity of liquid delivered. As hereshown, the arm 22 is provided at a point spaced from its axis with astud or projection 25 which extends into a cam slot 26 formed in oneface of a cam disk 27 rigidly secured to the shaft 6. This arm 22 isconnected with the actuating device for the register by a rod 28 whichis pivotally connected at one end with the operating arm 21 of theregister actuating device and is pivotally connected at its other endwith the arm 22. This latter connection is adjustable toward and from.the axis of the arm 22, theend of the rod 28 being preferably slidablymounted on the arm. In the present instance, the arm 22 has an elongatedslot 29 extending lengthwise thereof and the lower end of the arm 28carries a projection or stud 30 which extends into and travels in theslot 29. It will be apparent. therefore, that when the connecting stud30 is in its outer portion in the slot 29, that is. the position spacedfurthest from the axis of the arm, the movement of the arm will betransmitted through the rod 28 to the register actuating device and thismovement. will be suflicient to advance the register upon each operationof the arm. \Vhen the connecting stud is moved to the inner portion ofthe slot 29, adjacent to the axis of the arm. the movement imparted byhe arm to the rod 28 will be so slight that it will not impartoperative. movement to the register opby the arm 33 of thebell cr'anklever this device the cam block 34 has secured crating device andconsequently the connection between the umping mechanism and theregister operating device will be inoperative. The position of theconnection between the rod 28 and the arm 22 is controlled by theposition of the by-pass valve 28 and, in this form of the device, ,abell crank lever 31 is pivotally mounted on a block 34 is rigidlysecured to the valve stem and provided with a cam slot 35 into whichextends a projection or stud 36 carried In thereto an operating handle37 by means'of which the by-pass valve is actuated. It will be apparent,therefore, that when the bypass valve is in its normal position, asshown in Fig. 1, the connection between the rod 28 and the connectingarm 22 will be spaced from the axis of the arm such a distance as torender the connection between the pump ing mechanism and the registeringdevice operative, but when the b'y-pass valve has been actuated todivert the liquid through the bypass this connection will be moved to apoint adjacent to the axis of the arm 22 so that only a very slightmovement will be imparted to the operating arm 21 and this movement willnot move the pawl sufficiently to cause the ratchet wheel to beoperated, thereby rendering the connection between the pumping mechanismand the registering de vice inoperative.

The apparatus is also provided with an audible signal here shown in theform of a bell 38 mounted on the frame 12 and having associatedtherewith a bell tapper 39. In the present construction, this belltapper is carried by one arm 40 of a bell crank lever which is pivotallymounted at 41 and has at its other end a nose 42 arranged to be engagedby a projection 43 carried by a bell actuating member or plate 44, whichplate'is capable of vertical movement. The arrange ment is such that theupward movement of the plate 44 will move the bell crank lever, aboutits axis and retract the bell tapper and as the plate reaches the upperlimit of its movement the projection 43 will clear the nose 42 of thelever and release the bell tapper so that the latter may be moveddownwardly by a suitable spring. In the present device this spring isshown at 45 as connected with a laterally extending portion 46formingpart of the arm 40 of the bell crank lever. The bell actuatingmember or plate 44 may be operated through any. suitable connection withthe pumping mechanism which willcause it to be operated atf'the propertime and inasmuch asthis connection forms no part of the invention it isnot here shown. The connecting rod 28 is so arrange'dthat when this rodhas ,been moved into a position to V interrupt the connection bet-weenthe pumping mechanism and the registering device it willengage a partcar-' ried by the extension 46 of thebell'crank lever and hold thebell'tapper in'an inoperative. position. Ashere shown, the connecting rod 28is soarrange'd that when in its in operative positionit'will engage apin 47 bymeans of which the spring 45 is connected withthe-ext-ensibn 46o'f'the lever. When the connecting rod is in its'operative position itwill be spaced-{such a distance from pin 47 that it-wi-ll'not interferewith the operationof th b taPp-er. V I

In that form of the "apparatus showin in Figs. 4to 9, theconnectionbetween the reg-- istering device and the puinpingmechanisnr comprisesan arm50 prv'otallyfmountedon a stud 51 carried by the frame '12,'anda-connecting rod 52 is pivotally connected at its respective ends withthe arm 50 and the operating arm 21 of the register actuating device.Movement is imparted to the connecting arm 50 through the medium of asecond arm-53 which, in the present instance, is also mounted on thestud 51 and which is provided with a projection or stud 54 extendinginto the cam slot 55'formed in one face of a cam disk 56 secured to theshaft 6. The lower end of the arm 53 has pivotally connected therewith alink 57 the opposite end of which is pivotally connected with the lowerend of a second link 58, by means of a pin 59, and the upper en'd'ofthis link 58 is pivotally connected with the connecting arm 50. In thepresent instance, the upper end of the link 58 is connected with the arm50 by a pin 60 which also serves to connect the lower end of theconnecting rod 52 to that arm, thus the link 58 extends substantially inline with the rod 52. A controlling arm 61 is connected with the links57 and 58 and is preferably pivotally mounted on the pin 59 by means ofwhich these links are con-. nected. This controlling arm extends up-.wardly to a point adjacent to the connecting arm and is pivotallyconnected to the free end of an arm 62 which is pivotally mounted andwill therefore impart no movement to the connecting arm"50, theconnection between the pumping mechanism and the'regthus renderedinoperaistering devise bein tive. The adjust-a le fulcrum or pivotalconnection between thearms 61 and 62 is shifted by means under thecontrol of the bypass valve 8. In the present device, an arm 64Jis'mounted on the stud 63. and rigidly connected with' the arm 62. Aconnecting rod 65 is connected at its upper end with the rod 64 and atits lower end with a lever 66 pivotally mounted on a bracket 67 carriedby one o'f thestandards 11. This lever is acted upon by a cam connectedlwitlrthe valve stem 10 and, as here shown this cam is in the form of alaterally extending plate68 which] extends between two projections orrollers 69 carried by the lever 66 so' that the movement of the camplate 68 about the axis of the valvestem will cause the lever 66 L0 7 berocked about its axis,'tl1ereby imparting movement to the arm 64 andcausing the adjustable fulcrum tobe moved from one position to theother. A

This form of the apparatus is'also provided with an audible signal,which is shown as a bell 70 mounted on the frame 12 and havingassociated therewith abell tapper 71' which is carried by the hub of anarm 72 pivotally mounted adjacent thereto and preferably on the stud 51which carries the connecting arm 50. A spring 73 acts on the arm 72 tomove.the bell tapper toward the lin bel tapper arm 72 will move that armabout "its'axis to retract the bell tapper and will hold thetapperretracted soslong as the conbell, and the arm 72 is actuated to retractthe bell tapper by means of a dog 74 pivotally "mounted" referably onthe stud that supports the be 1, and arranged to engage a projection 75carried by the arm 72 above its axis. The dog is connected throughsuit-.

able mechanism with the pumping apparatus which will cause it to beoperated at the proper time but inasmuch as the means for actuating thisdog forms no part of athe present invention it is not here shown ordescribed. That edge of the bell tapper con trolling arm 72 ad acent tothe controlling arm 64 is inclined or provided witha cam surface, asshown at 76, over which the end of the controlling arm will ride whenthat arm is aetuatedto render the connection between the pumpingmechanism and the re ister inoperative. The length of the c'ontrfi armissuch that its contact with the nection between the pumping mechanismand the registering device is inoperative, that is, so long as theby-pass valve is open,

While we have shown and described one embodiment of my invention we wishit to be understood that we do not desire to be, limited to the detailsthereof as various modifications may appear to a person skilled in theart.
